I just finished this question the answers D.) C6H1206
Ecotourism
d. increases biodiversity by providing income to areas that might otherwise be destroyed
Explanation:
Ecotourism refers to visiting of undisturbed natural areas.
Ecotourism is different from other tourism on the fact that it does not involve visit to an area which is maintained by humans.
Ecotourists spots are allowed to grow naturally so that they can drag people who really want to enjoy the nature.
Ecotourist spots are protected areas and taxes are levied on them.
Ecotourist spots call for tourists and gives native people ,a way of earning.
This forces the people to maintain these spots and hence biodiversity is conserved.
Answer:
D) Na+ is used to repolarize the membrane.
Explanation:
Option D is wrong choice because it is K+ which is used to repolarize the membrane not Na+.
As soon as membrane gets depolarized because of influx of Na+ due to opening of voltage gated Na+ channels simultaneous opening of voltage gated K+ channels and closing of Na+ voltage gated channels takes place. As a result of which K+ moves out of the cell leading to drawing of electrochemical gradient out of the cell.
In order to achieve resting membrane potential, more Na+ must be out of the cell and more K+ must be inside the cell. There are many leaky channels on neurons from which Na+ has tendency to leak into the cell while K+ has the tendency to leak outside of the cell. So Na+/K+ pump which is located on the membrane of neuron keeps pushing Na+ outside of the cell and K+ inside the cell so as to maintain resting membrane potential which is -70 mV.
<h3><u>Question</u><u>:</u><u>-</u></h3>
Which of the following are reactants of cellular respiration?
glucose, water, carbon dioxide
water and glucose
carbon dioxide and glucose
oxygen and glucose
<h3><u>Answer</u><u>:</u><u>-</u></h3>
glucose, water, carbon dioxide
<h3><u>Explanation:</u><u>-</u></h3>
Cellular or aerobic respiration is a series of chemical reactions that begin with a sugar reactant in the presence of oxygen and produce carbon dioxide and water as waste.
